Audionet EPX

Energize Your Gear

The EPX is Audionet’s scientifically proven answer to very serious music lovers desperately wanting to enhance the performance of their already existing devices with a High Performance upgrade.

The EPX produces clearly audible improvement in terms of stability, calmness, spatiality and tonal pureness. Music is reproduced with greater naturalness, clearer expression and in a brighter quality. Its straight design fits in every configuration.

Why does an external power supply represent such an improvement? The properties of active circuits are highly dependent on their supply voltages. Devices designed for the reproduction of music are very sensitive to any kind of external supply variations. As a voltage source, the EPX offers extremely precise and load-independent supply voltages. With these properties, EPX comes close to an ideal voltage source without accepting the disadvantages of accumulators.

The EPX achieves effective decoupling of all harmful influences from the public power supply system. The EPX is fed by a constant, low-noise source usually only used in laboratory environments. This precise constant voltage supply will really make the decisive difference to the performance of your devices.

Absolute Control

The EPX is built up as a high-precision constant voltage source. The chassis and circuit design are magnetically and capacitatively optimized. The symmetrical circuit board layout minimizes loss from oversized current paths and earths the current flow.

The arrangement of the toroid core transformers minimizes the influence of magnetic disturbances. The voltage supply is managed by two 200 VA ring toroid transformers that are each responsible for one half-wave. The capacity of the fast and impulse-stable high current capacitors is 576,000 uF. Only Schottky-diodes with extremely fast switching times are used. A highly constant and low-noise laboratory source serves as voltage reference.

Positive Feedback

Together with PRE G2, PAM G2, and MAX
“The EPX does the job of taking the PAM G2 to another level of purity and performance. The task of retrieving the very low signals from MCs is a delicate one; poor handling of the power supply in a phono amp will lead to degradation of the handling of the input signal. The EPX is Audionet’s effort to minimize such signal corruption in their attached devices.”

HiFi & Records

Test DNP with EPX:
“[…] The combination with the high precision external power supply EPX results in an audiophile Bi-Turbo, which seems to be without any alternative for me […] The signal-to-noise-ratio is so low, that it is nearly not detectably. State of the Art – as good as it gets”
